Are supercharger and charging supercharger the same thing?

Yes. "Supercharger" and "Charging supercharger" refer to the same car part. Other common names include Charging supercharger, Supercharger Unit, Mechanical Supercharger. The part is the same regardless of which name is used.

What is the difference between a supercharger and a turbocharger?

A supercharger is mechanically driven by the engine via a belt or chain, delivering instant boost with no lag. A turbocharger is driven by exhaust gases, so boost builds with engine revs. Superchargers are less efficient but more responsive at low speeds.

How long does a supercharger last?

Most factory-fitted superchargers last 100,000+ miles with correct maintenance. Performance-focused aftermarket units under heavy use may require more frequent servicing of bearings and seals.

What oil does a supercharger use?

Many superchargers have their own small oil reservoir using a specific grade of synthetic gear oil. Check the manufacturer's specification — using the wrong oil or running low causes rapid bearing wear.

Can a supercharger be rebuilt?

Yes. Specialist rebuild kits are available covering bearings, seals, and rotors. Rebuilding is cost-effective for expensive OEM units but requires specialist tools and clearance gauges.

What are the signs of a boost leak?

A boost leak from deteriorated supercharger hoses causes a hissing sound under acceleration, reduced power, and possibly a lean mixture fault code. Pressurising the intake system with low-pressure air identifies the leak location.
